One spring, many years ago, Esther Woolfson's daughter rescued a fledgling rook. That rook, named Chicken, quickly established herself as part of the family, and other birds, including an irascible cockatiel and a depressive parrot, soon followed. But it was the corvids - members of the crow family - who amazed Woolfson with their personality and their capacity for affection. This classic blend of memoir and natural history combines the author's fascination with all things avian, from the mechanics of flight to the science of birdsong, with her funny, tender stories of life among the birds.
